GAS GENERATOR AND BURNER.

Application filed June 1'7, 1918.

To aZZ whom it may concern:

Be it known that I, Eowano ll). ElMALL, a

citizen of the United mates, and a resident of Portland, in the countyof Multnomah and State of @regon, have made certain new and usefulimprovements in Genera tors and Burners, of which the following is aspecification.

This invention relates to an improvement in gas generators burners, andone of the principal objects thereof is to provide an improved gasgenerator and burnerespecially adapted for use in ranges, heatingstoves, furnaces and the like.

Another object of the invention is to pro vide an improved generator andburner adapted to use coal oil as a fuel, the construction being suchthat the oil is volatilized in a chamber forming part of the burner andis fed in the form of gas from a hollow linger communicating with thechant her, the means for vaporizing and feeding the being contained inthe burner.

Another object of the invention is to pro vide an improved generator andburner which will be extremely simple, durable, efficient in operationand inexpensive to manufacture. With these and other objects in viewwhich will become apparent as the description proceeds, the inventionresides in the construction, combinations and arrange ment of partshereinafter more fully described and claimed and illustrated in theaccompanying drawing in which like characters of reference indicate likeparts throughout the several figures of which,

Figure 1 represents a vertical sectional view taken through the burnerand generator constructed in accordance with my invention.

Fig. 2 represents a side elevational view thereof.

Fig. 3 represents a horizontal sectional view taken on the planeindicated by the line 33 of Fig. 1.

Fig. at represents a plan view of the plate used for spreading theflame. I

Fig. 5 represents a transverse sectional view taken through the plate.

Referring more particularly to the drawing, 1 indicates an annular paninto which a small amount of oil is fed in order to start the burner.This oil is drawn from a reservoir or tank, not shown, through a pipe,not shown, and enters through an opening 10 provided in the bottom ofthe pan. The

Specification of Letters Patent.

Patented Feb. 3, 1920.

Serial No. 304,756.

pan is arranged below the burner which consists of a lower annular gaschamber 9, and an upper annular gas chamber 8 connected on the side ofthe burner through a passage 11 arranged at one side of the body of theburner, such passage being of relatively large cross sectional area inorder to allow for circulation of gas from the lower to the upperchambers.

The burner has a central air passage 12 eX-- tending therethrough, thispassage being enlarged as at 13 in the body of the burner between theupper and lower gas chambers, and arranged in the enlarged portion 13and restin on the lower wall thereof is a flame spreader or plate 4;provided with a central rib 14. This plate is used for the purpose ofspreading the flame in the body of the burner.

Connecting with the upper gas chamber 8, at a point diametricallyopposed to the passage 11, is a hollow finger 15 which curves upwardlyand over toward the center of the burner, said finger being providedwith a restricted port 7 arranged approximately in alinement with thepassage 12 through the burner.

Oil for the burner may be fed through a pipe to the inlet tube 2communicating with the lower gas chamber 9 and which projects downthrough the pan 1. From the forego ing description taken in connectionwith the drawing, the operation of the burner will be readilyunderstood. Oil may be fed to the lower gas chamber through the tube 2.Upon starting the burner a small quantity of oil is drawn into the pan 1and ignited. The flames from this oil will impinge against the body ofthe burner, thus raising its temperature sufiiciently to volatilize theoil as it is fed into the lower gas chamber.

The gas thus generated finds its way up through the passage 11, into theupper chamber 8 and from there through the finger 15 to the port 7, fromwhich it is directed down wardly through the upper end of the airpassage 6 against the flame spreader or plate 4t. The flames from thepan 1, before the pan has burned out will ignite the gas as the latteris ejected from the port 7. The flame directed into the body of theburner will serve to maintain the temperature of the gas chamberssufliciently high to continue the volatilization of the oil as it is fedto the burner.

Although I have described the preferred embodiment of my invention, Imay desire to make such changes in the construction, combination andarrangement of parts thereof, as do not depart from the spirit of theinvention and of the scope of the m pended claim.

I; claim:

A gas generator and burner comprising a body formed to provide spacedupper and lower annular chambers and having formed in ones ide a:passagecommunicating With said chamb'ers, said body being providedcentrally with a relatively lar e chamber in non-commun catlng relationto said first named chambers and, being further provlded with openingscommunicating with said cen tral chamber and leading through the top andbottom of the body, a pipe member rising from said body at its sideopposite said passage and communicating with the upper of said firstnamed chambers, said pipe being curved to extend over the center of saidopenings and being provided with a perforation in alinement with thelongi tudinal axis of said openings, a plate disposed within saidcentral chamber, and a priming pan beneath said body, the lowermost ofsaid first named chambers being adapted for connection with a fuelsupply.
